+As a person who is interacting with data, it is crucial to understand how the data is delivered.
+
+In the engineering realm, engineers are using the terms Service Level Agreements (SLA), Service Level Objectives (SLO), and Service Level Indicators (SLI), to align on the mutual understanding of the system.
+
+In the data world, it is also crucial to read them whenever they are available.
